Science fiction has always been fascinated with what lies beyond our planet, but some of the genre's most memorable stories unfold on a single, exotic alien world. These are the planetary romances—tales that prioritize personal heroics, strange cultures, and daring quests over high-tech space battles. The term "romance" here isn't just about love; it's about adventure, wonder, and the thrill of the unknown. From silent-era pioneers to modern blockbusters, these films have defined the subgenre and continue to inspire. Here are the greatest planetary romance movies of all time, ranked.
10. The Space Between Us (2017)
Directed by Peter Chelsom, The Space Between Us follows Gardner Elliot (Asa Butterfield), the first human born on Mars.
